FlangeFeatureDefinition Object Preview

Derived from: Base Object
Defined in namespace "adsk::fusion" and the header file is <Fusion/SheetMetal/FlangeFeatureDefinition.h>

PreviewThis functionality is provided as a preview of intended future API capabilities. You are encouraged to use it and report any problems or suggestions using the Fusion API and Scripts forum.

Because this is a preview of future functionality, there is the possibility that it will change, which will possibly break any existing programs that use this functionality. Because of that, you should never deliver any programs that use any preview capabilities. For a distributed program, you should wait until it has moved from preview to released state.

Description

Base class for edge, base and contour flange feature definitions used when reading or editing existing flange features.

Methods

Name Description
classType

Static function that all classes support that returns the type of the class as a string. The returned string matches the string returned by the objectType property. For example if you have a reference to an object and you want to check if it's a SketchLine you can use myObject.objectType == fusion.SketchLine.classType().

Properties

Name Description
isValid Indicates if this object is still valid, i.e. hasn't been deleted or some other action done to invalidate the reference.
objectType This property is supported by all objects in the API and returns a string that contains the full name (namespace::objecttype) describing the type of the object.

It's often useful to use this in combination with the classType method to see if an object is a certain type. For example: if obj.objectType == adsk.core.Point3D.classType():

Samples

Name Description
Flange Feature Sample

Demonstrates accessing and creating sheet metal flange features including base flange, contour flange, and edge flange.

To run the sample script, have a design open in Fusion's DESIGN workspace that contains a sheet metal body in the root component. The body must have at least one linear edge on its outside that is valid for a flange. A design created with the Sheet Metal > Create > Flange commands, or any design containing a base flange, satisfies this.

The script first iterates over any flange features that already exist in the design and reads the settings from each definition, so the reading portion reports nothing if the design has no flanges yet. It then finds the first linear edge on the first body in the root component and uses it to create a new edge flange feature. Reading the edges back from the created feature requires rolling the timeline marker to immediately before the feature, which the script does using TimelineObject.rollTo.
